adds a deploy button to the panel form - covers the local part of #76.
As a workaround to pass info (from our user form) into nixops4 uses
environment variable `DEPLOYMENT` thru nix's
`--extra-experimental-features configurable-impure-env`.
- simplify the configuration module
the `package` attribute makes little sense to be user-configurable,
since it will always need to be the derivation defined in this very
repository. for debugging one may as well change the original code itself.
- unbreak deployment
setting `CREDENTIALS_DIRECTORY` disabled the systemd mechanism set up
in the configuration module.
- remove unneeded configuration for deployment
- unbreak integration tests
before that missed waiting for the service to create some
state before running the application-level tests.
This setup is greatly inspired by the one used for [0], although with
notable modifications, such as:
- a SASS preprocessor and CSS compressor
- more streamlined NixOS integration tests
- cleaned up service configuration
- a few notes on how to do things better in the future

Apart from cloning the Nix setup, there were additional steps:
- Create an empty `src` directory, since the package requires it
- In the development shell, run `django-admin startproject panel src`
Note that while you can already do
```bash
manage migrate
manage runserver
```
the NixOS integration tests will fail, since `settings.py` needs
careful massaging to expose knobs that can be turned from our systemd
wrapper. The required changes are introduced in the next commit to make
them observable.

module system, in particular secrets.

Out of date and somewhat simplistic, but serves as a reasonable
example for what can be done
I chose the variant I'm intimately familiar with in order to be able to
pass on knowledge or help with maintenance. But for the future
I strongly recommend picking the good bits from the other
implementations that control complexity in static configuration parts
through Nix expressions.
